Inside a large industrial building are three indoor tracks with computer lap timing and track crews directing races.

KCRA 3 News saw adults racing until midnight Friday, enjoying the new facility that began operations last week.

“We’re still finishing staff training and waiting for more furniture but we’re ready,” said general manager Duane Brown.

The karts are powered by nine-horsepower Honda motors on a Sodi chassis, made in France.

“These go-karts handle well and go really fast for a real racing experience,” said owner David Robison. “If you’re not using the brakes you’ll end up in the wall probably.”

Robison said his first location in Burlingame has been a big success, with more than 300,000 riders without a serious accident.

He said many celebrities have enjoyed the sport in the Bay Area, including 49ers quarterback Colin Kaepernick.

Robison said the karts are not toys or amusement park bumper cars.

“If you ride them hard, it’s physical. You’re going to get a workout,” said one driver.

Riders are required to sign a legal waiver and watch a safety video to learn the track rules and recognize warning flags.

They must also wear a racing jumpsuit and a snug fitting helmet.

Assistants make sure each person is secured in the kart’s four point harness with a neck brace to prevent whiplash.

Drivers can purchase a session of hot lap for $25. A full race is $45.

Although mostly for adults and corporate team building events, the track does offer smaller karts for kids 8 to 11 and teens. Brown said the track will also host children’s racing-themed birthday parties.
